I'm feeling stupid. I used to have a math package which inverted
matrices to solve systems of linear equations - i.e. enter the matrix
and the y values and the program inverts the matrix and reports the x

matrices. Perhaps Openoffice.calc/solver does this but it is not clear
to me how to enter data for solver to do this. apt-cache search matrix
|grep inversion doesn't turn up anything.
Would someone please beat me over the head and point me to a simple
package to do this job?
Software suites:
Matlab - proprietary, comes with a good GUI, lots of routines to plot
graphs, contours etc., contains lot of sparse solvers.
Octave - Use versions > 2.9.12 for better experience. Older versions are
incompatible with newer versions. Does not have a GUI provided by the
